Open End Spline Drive Tuner Lug Nuts 12x1.25 Blue

6-Spline tuner style blue finish open end lug nuts 12mmx1.25 thread size with key. The hex key has both 3/4" and 13/16" head. The lugs are heat treated to achieve extra strength. Our application guide page will answer most of your application fitment questions but do not hesitate to ask us.

Fitment and specs

• Thread size: 12x1.25 (12mm stud, 1.25mm thread pitch)
• Open end, 6-spline tuner style design
• Comes with a spline key; the key's hex head fits 3/4 inch and 13/16 inch sockets
• Heat treated for extra strength
• Blue finish

Start each nut by hand to protect the fine threads, tighten in a star pattern, and bring everything to final spec with a torque wrench using our torque reference chart. A torque wrench instead of an impact gun also keeps the blue finish clean. Re-torque after 50 to 100 miles.

Common questions

Is the key included?
Yes. A 6-spline key ships with the lug nuts, and its dual hex head works with either a 3/4 inch or 13/16 inch socket. Standard sockets will not grip the spline pattern itself, so keep the key with your roadside tools.

Will these fit my wheels?
Your studs must be threaded exactly 12x1.25, and your wheels' lug seats must match the seat type of the nut, since conical, mag, and ball seats are not interchangeable. The open end also means longer studs can pass through without bottoming out.
